Patented July '7, 19,14.,

Application f led February 9, 1914. Serial N o. 817,432.

To all lwhom it may concern:

Be it known that I, LEOPOLD BoT'rENs'rniN, a citizen of the UnitedStates, residing at Albany, in the county of'Albany and State 5 of NewYork, have invented certain newm and useful Improvements inSmoke-VVashers, of which the following is a specification.

My invention relates to devices for eliminating the smoke nuisancecaused by burning soft coal in furnaces and boilersand the object of myinvention is to provide a means by which the cinders and soot containedin the smoke will be collected and washed out -by a spray of water. Iaccomplish this object by means of the mechanism illustrated in theaccompanying drawings, in which- IFigure l is a vertical section of asmoke stack equipped with my smoke Washer. Fig.

2 is a vertical section of a modification of my invention designed towash the' smoke from tlre inside of a smoke stack. Fig. 3 is a sectionof a spray pipe used for washing the smoke on the inside of the smokestack.

Figs. 4e and 5 are elevations of portions of said pipe with parts brokenaway showing the method of closing the holes. Fig. 6 is a cross sectionthrough the spray pipe B.

Similar letters refer to similar parts throughout the several views.

Referring to the drawings, A represents the shell of a chimney or smokestack of any desired construction. Above the top of said smoke stack Iconstruct a spray pipe B.

This pipe is supplied with water from the' pipe C. The pipe D isprovided with spray holes of any suitable form and size to produce asuitable spray above the top of the chimney. The chimney is providedwith the cover D of any suitable form and construction. This cover I)will force the smoke to pass through the spray formed from the pipe Baround the edges of the cover.

.E represents the spray from the pipe B. F is a weather-vane ofanysuitable form and construction having a shield G which will protect the'spray from the wind so that no matter/Which way the wind blows from theWeather-vane F, turning upon the pivot 50 H, Will carry the shield G soas to protect the spray from the force of the wind, so that the Windwill not interfere with the uniform spray from the pipe B and shield Gwill also protect the draft of the chimney. n

I is a gutter extending around the chimney or smoke stack to catch thewater from the sprayas 1t condenses and falls.

J is a gutter-pipe extending from the gutter I to carry the Waste fromthe spray to the ground, as may be desired.

The water of the spray will Wash out the soot and dirt contained in thesmoke caused by burning soft coal and collect the same in the gutter andcarry it through the gutter I to the waste pipe J olf with the Water tothe ground or to pockets Where it may be collected for use, as may bedesired.

In some cases it may be advantageous to have the spray and Wash thesmoke inside of the chimney. In such cases I provide the spray inside ofthe chimney as shown in Fig. 2. In that case the Water is supplied fromthe pipe C, as before stated, and the spray pipe B is substantially thesame as the spray pipe B shown in Fig. l, but instead of making thespray on the outside' of the chimney, asshown in Fig. 1, the spray isconfined Withinthe chimney, as shown in Fig. 2, or the spray may beformed in the center of the chimney and instead Of having the pipeextend around the inner side of the chimney, as shown in. the upper partof .said figure, the spray may be in the centerof the chimney, as shownby the pipe K in Fig. 2. The spray pipe may have holes which may beenlarged or contracted, as may be desired by the slides L, as shown inFigs. i and 5. These slides operate to .cover up portions of the holesin the spray pipe. Vhen the holes are mostly covered there will be avery fine spray and when the slide is operated the other Way so as tocompletely uncover the holes the spray will be coarse and Hood thechimney and waste pipes as may be desired. The slide L consists of aring covering the spray pipe, as shown in Figs. 3, 4, and 5.

The mechanical details of working out this invention may be varied tosuit thc circumstances without departing from thc spirit of myinvention.

`What I claim as my invention and desire to secure by Letters Patent is,

l. In a device for washing the soot and dirt from smoke, a spray pipeabove the top of achimney, a cover over said chimney` a weathervanelocated at 'the top of said chimney. a shield attached to saidweathervane which shield is adapted to protect the spray from `the forceof the wind.

2. In a device for washing the soot. and

i, dirt from smoke, a spray pipe aboye the top l spray `from the forceof the Wind, a Water pipe to conduct Water to said spray and a Wastepipe to vconduct the saine away.

3. In a device for Washing the soot and dirt from smoke, a spray pipeabove the top of a Chinmoy, a cover over said chimney, a Weatherfvanelocated at the top of said chimney, a shield attached to saidWeathervane which shield is adapted to protect the spray from the' forceof the Wind, a ,Water pipe to conduct Water to said spray pipe, a gutterto collect the Water from said spray, 'a Waste pipe to conduct the `Sameaway, a slide on the outside of said spray pipe whereby the size of theopenings in said pipe may be partially closed, substantially asdescribed for the purposes set forth.

In testimony whereof I aiiX my signature in presence of twowitnesses.
